Summary
In this chapter, we have explored how to develop a low-cost, multi-color smart table lamp for our room using the XIAO ESP32C3 and WS2812. We have set up the Thing, which included cloud variable creation, device association, network configuration, and coding of the development board. Later, we created a dashboard using different widgets to control the WS2812 RGB ring. Finally, we used the Amazon Alexa voice assistant to turn our table lamp on/off and control its color and brightness with voice commands.
This chapter will give you the confidence to build more interesting stuff to make your home and office smarter. In the next chapter, we will talk about Cloud Scheduler and over-the-air update’ features. Both features are interesting and specially designed to carry out operations on IoT nodes.
